For the money, this is an excellent scenery package if you're flying a lot around Los Angeles or San Diego. The map provided with the screenshots here is accurate to the coverage area - from Santa Maria in the NW to the Arizona and Mexican borders on the other corner. Note that this is only photoscenery and the associated autogen, not a great deal else in terms of scenery object or airport enhancements. That said, the imagery is well sourced and just looks right in terms of coloration and contrast (from the eye of a SoCal native), and the autogen is plentiful and reasonably accurate, both trees and buildings. Also comes with built in night lighting and textures.
Framerate on my mid-to-high-range PC isn't terrible when flying around, at least in P3D v4; on approach to LatinVFR KSAN or FSDreamteam KLAX in the PMDG NGX, I see generally 15-20 fps, and pretty consistent 30+ flying over most other areas in the region.
Blend-masking with the surrounding terrain is reasonable. There are definitely places you'll see the border where it meets default terrain (not least because the border is 3 very long straight lines and the Pacific), but the transition isn't totally abrupt at least.
One other note: this scenery is gigantic (right around 40 GB installed), and if loading from an HDD the loading times will be quite long. Definitely put this on an SSD if you can.
4.5/5
